Cool your whole home evenly with a forced air AC, or install multiple ductless units for zone control in different rooms? This guide breaks down the pros and cons of central and ductless air conditioners so you can choose the best type for your needs.
During Nebraska’s hot and humid summers, your home needs cooling equipment your family can count on. Forced air and ductless ACs are both popular in the Cornhusker State, but choosing between these two types requires an understanding of how they differ and their ideal use cases.
Star City performs new air conditioner installations in Lincoln, NE and the surrounding area, including forced air and ductless models—so we know all about how they compare, and we’re here to give you an overview. Below, we cover the differences between forced air and ductless air conditioning systems, including their energy efficiency, costs, and more.
How Forced Air & Ductless ACs Work
Forced Air Systems
- These systems use ductwork and registers to distribute cooled air throughout the home.
- An outdoor unit holding the compressor and condenser connects via coolant lines to an indoor unit with the evaporator coils.
- As refrigerant circulates through this system, it undergoes state changes that pull heat out of your home’s air and distribute it outside.
- The furnace’s blower fan then circulates the treated air throughout the ducts and vents of your home.
- These systems (also known as mini-split systems) consist of individual units mounted on exterior walls instead of connecting to your furnace and ductwork.
- The outdoor portion of a ductless AC contains the compressor and condenser, while the indoor portion holds the evaporator coil and an air handler to push treated air into the home.
- Ductless systems work best in owner-occupied lofts, apartments, and smaller homes that do not have the capacity for ductwork. To cool an entire detached home, we recommend using a forced air system and potentially adding a ductless unit or two for additional cooling in specific areas.

Key Comparisons Between Forced Air & Ductless ACs
Energy Efficiency & Cooling Capacity
While ductless units tend to have slightly higher SEER (Seasonal Energy Efficiency Ratio) ratings, that doesn’t always make them the best choice. The type of AC that’s most efficient for you depends on where and how it will be used.
- Centrally ducted air conditioners are often more efficient in larger homes that require uniform cooling throughout. Controlling them from a single thermostat eliminates the risk of energy being wasted by accidentally leaving a unit running when it isn’t needed.
- Ductless air conditioners are generally the most efficient in smaller homes or those without suitable ductwork for central AC, especially when you only need to cool specific areas or adjust cooling in different parts of the home.
Climate Considerations in Nebraska
Nebraska’s average daily temperature is above 76°F during the summer, which lasts for nearly 4 months of the year. Either type of system can provide enough cooling for your home during this period, as long as you set it up correctly.
- Forced air systems must be sized by professional HVAC technicians to ensure that their cooling capacity (measured in Btu or British thermal units) is sufficient for your home.
- Ductless systems must be sized as well—plus, you’ll need to figure out how many individual units you need to purchase and install to cool the parts of your home that need it.
In either case, determining the right size of air conditioner for a given home is a complicated task that requires professional expertise, so always call our team for new AC installations in Lincoln, NE.
Costs, Savings & Maintenance
Ductless systems typically cost more upfront because you’ll have to buy multiple units to cool an entire home. However, the control and energy efficiency they offer can help offset those costs over time.
Both types of AC require some regular maintenance. Maintenance for forced air systems includes changing the filter regularly and keeping the ductwork clean, while ductless systems require the servicing of individual units and filter cleaning. Either way, you’ll want to schedule a professional AC tune-up at least once a year.
Indoor Air Quality & Health Risks
Ductless systems have no ductwork, so their impact on air quality in your home is minimal. Forced air systems can be upgraded with HEPA filters, UV air purifiers, and other special features to ensure that the air moving through your home’s ductwork is always pure and fresh. Our technicians at Star City can tell you more about making these upgrades if you’re having a forced air AC installed.
Tips for Improving AC Energy Efficiency
Forced Air Systems
- Proper Installation: Having your new AC installed by our professionals ensures that your ducts will be able to distribute air throughout the home without leaks or other issues that could waste energy and cost you unnecessary money.
- Regular Maintenance: Having your ductwork cleaned every few years and changing or cleaning your filters on a monthly basis during the cooling season prevents debris from impacting your air quality or blocking the ductwork and forcing the system to work too hard. Yearly tune-ups by our professionals can also help identify and solve minor issues before they turn into expensive problems.
- Smart Thermostats: Modern programmable thermostats can be controlled remotely and set to adjust automatically to your routines over time, all of which can reduce energy wastage.
- Exploring Incentives: ENERGY STAR provides numerous incentives for homeowners making energy-efficient home upgrades, which can lower the upfront cost by up to 30%. Talk to our team to learn more about how purchasing a new central AC unit could allow you to take advantage of programs like this one.
- Proper Placement: Correct positioning of the indoor units maximizes airflow and cooling efficiency. Our team can show you the best spots to place ductless AC units in your home.
- Regular Cleaning: Keeping the filters and coils clean is essential for maintaining the unit’s efficiency. Our team can perform annual maintenance for ductless systems as well as forced-air units.
- Zone Control: Using ductless systems strategically to cool only the parts of your home that need it can lead to significant energy savings over time, lowering your bills and offsetting the initial costs of these systems.
- Energy-Efficient Models: Choosing models with higher SEER ratings can contribute to long-term energy and cost savings. Our team can recommend plenty of modern, high-efficiency options.
Typically, central AC units have a higher environmental footprint than ductless systems—but this can be offset by investing in a newer, high-efficiency forced air model. While older forced air systems may have SEER ratings of 10 or less, new models are required to have ratings of at least 13—which can translate into energy savings of over 20%.
If your home is suitable for them, ductless systems are also an eco-friendly alternative. Not only do they have higher SEER ratings, but they also require fewer materials to build—making their overall carbon footprint lower in many cases.
Choosing the Right System
There’s no right answer when it comes to forced air vs. ductless air conditioners—that’s why you find both kinds all over Nebraska! But using the information above can help give you some valuable perspective and understand the recommendations you’ll get from our experts.
Having us install your new air conditioner is the best way to know that you’re choosing the right kind for your home and lifestyle. Contact Star City Heating & Cooling to get set up with a cooling system that keeps your home comfortable all season long.
How often do air conditioners need professional service?
Both systems should be serviced at least once a year, preferably before the cooling season begins. Book your AC tune-up with Star City here.
Can I install an AC by myself?
Not recommended—even choosing the right kind of air conditioner for your home is a task that requires professional expertise, and the installation process itself must be carefully performed to avoid errors. Contact Star City to install your new air conditioner in a way that ensures safety, complies with local codes, and provides optimal energy efficiency for your home.
Which type of air conditioner is better for older homes?
If your home is old enough that it has outdated ductwork (or no ductwork at all), then our team at Star City will be happy to provide estimates for installing new or replacement ductwork. We can also help you determine the best type of system for your needs after asking you a few quick questions about your home.
What cooling capacity does my new air conditioner need?
Choosing an air conditioner with the right cooling capacity is called “sizing”. The sizing process can be complicated, and must take numerous factors into account, including:
- Square Footage
- Climate Zone
- Ceiling Height
- Sunlight Exposure
- Insulation Quality
- Appliances and Electronics
- Number and Size of Windows and Doors
- Building Orientation
- Exterior Wall Construction
- Ductwork (if applicable)
- Shade around the Building
Consulting with our HVAC professionals is the best way to determine the appropriate cooling capacity for your space. Our team at Star City performs a complex calculation called the Manual-J to determine the right size for any new air conditioner we install.
